Hongda concrete pump truck is the Hongda Group's advanced experience at home and abroad, using modern advanced computer simulation technology to systematically analyze the impact of various parameters such as stress, displacement and natural frequency on the fatigue life of the boom. Optimized design of the hydraulic system, using new free fluid technology, the first officer to reduce the impact of pumping commutation on the boom, obtained a number of patents in the optimization of the pump boom structure and hydraulic system design. Perfect product quality Control, excellence in product manufacturing, meticulous quality inspection, Hongda pump reaches domestic leading, international advanced level, all steel plates of the boom system are all high-strength cold-rolled steel plates of Swedish SSAB company, the yield strength is above 900Mpa, ensuring the boom The system has high strength, light weight, 100% of the boom system, the distribution pole, the fuel tank, etc., and the post-weld stress treatment. Each weld of the boom system undergoes 100% flawless inspection or X-ray photographs to prevent any details from being hidden. Defects, durability and better performance.

The slewing bearing of the boom system adopts the products of Roth Eide of Germany or La Rio Lisa of Italy, and the material is 42CrMo, which has higher strength and service life.

Accurate data support through finite element analysis and dynamic simulation analysis is used as the design basis to ensure the structure of the boom system is reasonable and the performance is excellent. The stress-strain detection by the national testing center verifies that the calculation results of the boom structure are consistent with the actual working conditions. Sex. Hongda pump truck adopts international procurement, and all key components adopt international famous brands, which have the following characteristics:

Large diameter conveying cylinder, good suction and pumping flow.

The imported German HBC infinite remote control device is light in weight and easy to carry. It can be operated with only the handle and the cloth boom can be accurately placed.

1. The pumping quantity can be adjusted steplessly;

2. The pumping speed of the pumping truck has stepless adjustment of speed and slow speed.

3. Stepless adjustment of the boom rotation speed;

4. Equipped with emergency braking device, diesel engine automatic lifting speed device, saving fuel consumption.
